Does anybody know the phone used in Gossip Girl pilot?

Does anybody know the cell phone used in the pilot of Gossip Girl? I really love the one used by Blair's friends Isabel Coates and Kati Farkas at the'kiss on the lips'party. They use it on a side and the screen kinda pops/opens up, I think there is a QWERTY keyboard underneath it but I'm not sure. They also use the phone when they get the news from gossip girl that Serena is back. I would love to know what phone it is, I really want one!

was it a sidekick??

i believe thelg enV or theSidekick
